3.HARDWARE SETUP

3.6Central Processing Unit (CPU)

The motherboard supports two A-type sockets (462 for dual CPU installation. Only AMD® AthlonMP processors may be installed; each CPU should be rated for the same FSB speed, but the rated speed for each CPU need not be the same. For single processor operation, use any type of AMD® Athlon/Duronprocessor. Attach a fan and heatsink onto the CPU to prevent overheating.

1.Locate the CPU socket. Open it by pulling the lever gently sideways away from the socket. Then lift the lever upwards. The socket lever must be fully opened (90 to 100 degrees).

2.Insert the CPU with the correct orientation: the notched corner of the CPU must be oriented toward the inner corner of the socket base nearest to the lever hinge.

CAUTION! The CPU fits in one orientation and should drop easily into place. Do not force the CPU into the socket to avoid bending the pins. If the CPU does not fit, check its alignment and look for bent pins.

3. Once completely inserted, press the CPU

firmly and close the socket lever until it snaps into its locked position.

4.Place a CPU fan and heatsink over the CPU. The heatsink should entirely cover the CPU. Carefully attach the heatsink locking brace to the plastic clips on the socket base. No extra force is required to keep the CPU in place.

CAUTION! Take care not to scrape the motherboard surface when mounting a clamp-style processor fan, or damage may occur. When mounting a heatsink onto your CPU, ensure that exposed CPU capacitors do not touch the heatsink, or else damage may occur! Refer to heatsink/CPU documentation.

NOTE! To avoid start-up problems, adjust the correct Bus Frequency and Multiples. (See: 3.4 Motherboard Settings and, 4.4.Advanced BIOS.)
